When to worry about chills with malaria

Most people with Malaria notice episodes that may move from chills and shivering to fever and sweating. Headache, body aches, marked tiredness, nausea, or vomiting may occur as well. Episodes can recur, and feeling better between them does not prove that the infection has cleared. Chills are a symptom, not a way to identify malaria by themselves; travel or residence in an area where malaria occurs is relevant to the assessment.

Anyone with a feverish illness after possible mosquito exposure should tell a clinician promptly, especially after travel. Malaria can become serious when the illness affects the brain, breathing, circulation, blood sugar, or ability to stay hydrated.

Seek medical advice promptly for suspected malaria rather than waiting for another episode. Record when the chills and fever occur, where you have travelled, mosquito exposure, medicines taken, and whether vomiting is present. Sip fluids if able, rest, and follow prescribed treatment exactly. Do not rely on insect-repellent measures or fever relief alone once illness has started, and do not use someone else’s antimalarial medicine.

Go to emergency care for confusion, unusual sleepiness, seizure, fainting, severe breathing difficulty, inability to drink, repeated vomiting, severe weakness, yellowing of the eyes, dark urine, or rapidly worsening illness. Treat suspected malaria as urgent after travel even if the fever settles temporarily. Children, pregnant people, and people with reduced immunity need especially prompt assessment.

Ask which tests are needed, when results should be repeated, and what treatment and follow-up are appropriate. Share travel dates and locations, preventive medicines, pregnancy status, previous malaria, fever pattern, vomiting, confusion, and every medicine or supplement you use.
